Network Requirements for Outgoing Call Routing

When establishing a call over a dynamic access facility, the switch
must inform the network of the type of service requested and the
destination of the call so that it can be properly handled. On
robbed-bit facilities, the dialed digits provide this information.
For example:
SDS domestic calls are identified by "700" numbers. More
specifically, the numbering format for 56 Kbps SDS calls is
700-56X-XXXX while ISDN 56 or 64 Kbps calls are in the
format 700-737-XXXX.
International SDS calls are prefixed with a "173." To place
international SDS calls, the user must dial 173+CC+NN, where
173 is the service identifier, CC is the country code (for
example, 44 is used for the U.K.), and NN is the destination
number in a format that complies with the destination
country's numbering plan.
SDDN calls are prefixed with "115" to identify to the SDN that
the call is a 56 Kbps data call. To place SDDN calls, the user
must dial 115-NNN-NNNN, where the last 7 digits are the
SDN destination number. For 64 Kbps data calls, an ISDN PRI
message is used to convey this information to the network.
The insertion of these service identifiers can be done automatically
by the AAR/ARS software in the switch such that it is transparent
to the user. Note that if ISDN PRI access is used, the "115" and
"173" identifiers are not required for SDDN and international SDS
calls since the service identification information will be conveyed
in an ISDN message.
For static access, where only one service is supported by an access
facility, a service identifier is not required.
In this section, an example of a switched application will be
presented to describe a typical HSL configuration and the steps
needed to administer this application. The application and
configuration presented here is not the only one available to the
HSL. Instead, the intent is to give the reader a basic
understanding of HSL switched applications.
Application Description
In this application the customer has a DEFINITY Generic 1 that is
connected to a DEFINITY Generic 2.1 via SDN. In addition to the
voice traffic that is carried by the SDN, the customer wants to
have the capability of making 112 Kbps video calls from both sites
over SDDN.
